2010-07-30virtio-serial: Check if more max_ports specified than we can handleAmit Shah1-1/+9
Currently virtio-serial supports a maximum of 31 ports. Specifying the 'max_ports' parameter to be > 31 on the cmd line causes badness. Ensure we initialise virtio-serial only if max_ports is within the supported range. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-07-30linux-user: fix build on hosts not using guest baseAurelien Jarno2-7/+9
Commit 68a1c816868b3e35a1da698af412b29e61b1948a broke qemu on hosts not using guest base. It uses reserved_va unconditionally in mmap.c. To avoid to many #ifdef #endif blocks, define RESERVED_VA as either reserved_va or 0ul, and use it instead of reserved_va, similarly to what has been done with guest_base/GUEST_BASE.

2010-07-29linux-user: Re-use load_elf_image for the main binary.Richard Henderson1-277/+103
This requires moving the PT_INTERP extraction and GUEST_BASE handling into load_elf_image. Key this off a non-null pointer argument to receive the interpreter name. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2010-07-29linux-user: Extract load_elf_image from load_elf_interp.Richard Henderson1-174/+167
Moving toward a single copy of the elf binary loading code. Fill in the details of the loaded image into a struct image_info. Adjust create_elf_tables to read from such structures instead of from a collection of passed arguments. Don't return error values from load_elf_interp; always exit(-1) with a message to stderr. Collect elf_interpreter handling in load_elf_binary to a common spot. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2010-07-29linux-user: Remove partial support for a.out interpreters.Richard Henderson1-70/+9
At the bottom of the a.out support was the unimplemented load_aout_interp function. There were other portions of the support that didn't look right; when I went to look in the Linux kernel for clarification, I found that the support for such interpreters has been removed from binfmt_elf. There doesn't seem to be any reason to keep this broken support in qemu. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2010-07-29linux-user: Put the stack guard page at the top.Richard Henderson1-14/+17
There are no supported stack-grows-up targets. We were putting the guard page at the highest address, i.e. the bottom of the stack. Use the maximum of host and guest page size for the guard size.

2010-07-29linux-user: Improve consistency checking in elf headers.Richard Henderson1-24/+33
Validate more fields of the elf header. Extract those checks into two common functions to be used in both load_elf_interp and load_elf_binary. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2010-07-29linux-user: Load symbols from the interpreter.Richard Henderson1-88/+101
First, adjust load_symbols to accept a load_bias parameter. At the same time, read the entire section header table in one go, use pread instead f lseek+read for the symbol and string tables, and properly free allocated structures on error exit paths. Second, adjust load_elf_interp to compute load_bias. This requires finding out the built-in load addresses. Which allows us to honor a pre-linked interpreter image when possible, and eliminate the hard-coded INTERP_MAP_SIZE value. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2010-07-29linux-user: Clean up byte-swapping in elfload.c.Richard Henderson1-71/+48

2010-07-29linux-user: Handle filesz < memsz for any PT_LOAD segment.Richard Henderson1-97/+55
I caught padzero not properly initializing the .bss segment on a statically linked Alpha program. Rather than a minimal patch, replace the gross code with a single mmap+memset. Share more code between load_elf_interp and load_elf_binary. Legally, an ELF program need not have just a single .bss; and PT_LOAD segment can have memsz > filesz.
